Heya user....!!!
HERE IS YOUR ANSWER
Aconvex mirror, or diverging mirror, is a curved mirror in which the reflective surface bulges toward the light source. A collimated (parallel) beam of light diverges (spreads out) after reflection from a convex mirror, since the normal to the surface differs with each spot on the mirror. Images are always virtual (rays haven't actually passed though the image), diminished (smaller), and upright . These features make convex mirrors very useful: everything appears smaller in the mirror, so they cover a wider field of view than a normal plane mirror does as the image is "compressed".A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). Unlike convex mirrors, concave mirrors show different types of image depending on the distance between the object and the mirror itself. These mirrors are called "converging" because they tend to collect light that falls on them, refocusing parallel incoming rays toward a focus. This is because the light is reflected at different angles, since the normal to the surface differs with each spot on the mirror.

Differences between convex and concave mirror:
Convex mirror:
1. The reflecting surface is curved outward.
2. After reflection from the mirror the light rays diverge.
3. The image formed due to convex mirror is always virtual and diminished.
4. It is used as rear view mirror.
Concave mirror:
1. The reflecting surface curved inward.
2. After reflection from the mirror the light rays converge.
3. The image formed due to concave mirror is generally real and either diminished or magnified. But when an object placed between vertex and focus it is virtual.
4. It is used in car headlights.
